The Healthy Nuts

Rules for snacking on nuts

• The recommended serving size for nuts is about a handful, or roughly one ounce. This is also all you need to get the energy-boosting and nutritional benefits.

• Although nuts are high in calories, they actually raise metabolism slightly with regular consumption. In one study, resting expenditure increased by 11 percent. If you're counting calories, reach for pistachios if possible and avoid high-calorie macadamia nuts.
